Pregnancy Headaches: Causes and Safe Remedies
Headaches during pregnancy can feel frustrating, especially when you are trying to be careful about everything you eat, drink, and take. Some pregnancy headaches are mild and related to everyday triggers like dehydration, fatigue, stress, posture, caffeine changes, or hormonal shifts. Others may need prompt medical attention.
This guide explains common causes of pregnancy headaches, safe remedies that may help, and when to call your healthcare provider.
Important: This article is for general education only and is not medical advice. Always ask your OB-GYN, midwife, or healthcare provider before taking any medication, supplement, herbal remedy, or new treatment during pregnancy.
Are Headaches Common During Pregnancy?
Yes, headaches can happen during pregnancy. Mayo Clinic notes that occasional headaches during pregnancy may be treated with acetaminophen for many pregnant people, but you should always check with your healthcare team before taking any new medicine or herbal treatment. Source
Headaches can be more common in early pregnancy because of hormonal changes, increased blood volume, nausea, fatigue, stress, and changes in caffeine intake. Later in pregnancy, headaches may also be connected to posture changes, poor sleep, tension, dehydration, or blood pressure concerns.
Common Causes of Pregnancy Headaches
1. Hormonal Changes
Hormone shifts in early pregnancy can affect how your body feels. Some moms notice more frequent headaches in the first trimester as their body adjusts.
2. Dehydration
Not drinking enough fluids can trigger headaches or make them worse, especially if you are also dealing with nausea or vomiting.
3. Low Blood Sugar
Going too long without eating may contribute to headaches for some pregnant women. Small, frequent meals or snacks may help keep energy more stable.
4. Fatigue and Poor Sleep
Pregnancy fatigue, nighttime bathroom trips, heartburn, discomfort, and anxiety can all interrupt sleep and contribute to headaches.
5. Caffeine Changes
If you suddenly reduce caffeine after becoming pregnant, you may experience caffeine withdrawal headaches. Ask your provider how much caffeine, if any, is safe for your pregnancy.
6. Stress and Tension
Stress, jaw tension, neck tightness, screen time, and posture changes can all contribute to tension headaches.
7. Sinus Congestion
Pregnancy can cause nasal congestion for some women, which may contribute to sinus pressure or headache-like discomfort.
Safe Remedies That May Help Pregnancy Headaches
1. Drink Water
Hydration is one of the simplest headache remedies during pregnancy. Keep a water bottle nearby and sip throughout the day, especially if you are nauseous, active, or spending time in warm weather.
2. Eat Small, Regular Snacks
Try not to go too long without food. Gentle options may include:
- Crackers with cheese
- Greek yogurt
- Fruit with nut butter
- Toast
- Oatmeal
- Soup
- Smoothies
3. Rest in a Quiet, Dark Room
If your headache feels worse with light, noise, or activity, rest may help. Try lying down in a calm room with dim lighting.
4. Try a Cold or Warm Compress
A cold compress on your forehead or a warm compress on your neck may help some types of headaches. Choose what feels more soothing.
5. Improve Posture
As pregnancy progresses, posture changes can add tension to your neck, shoulders, and back. Gentle stretching, supportive pillows, and regular movement breaks may help. Ask your provider before beginning new exercises.
6. Track Your Triggers
Tracking headaches can help you notice patterns and explain symptoms clearly to your provider.
Write down:
- Pregnancy week
- Time headache started
- Pain location
- What you ate and drank
- Sleep quality
- Stress level
- Screen time
- Any vision changes, dizziness, swelling, or nausea

Can You Take Acetaminophen for Pregnancy Headaches?
Many pregnant people can use acetaminophen for occasional headaches, but you should ask your healthcare provider first. ACOG says acetaminophen may be used when needed during pregnancy, but headaches can sometimes be a sign of preeclampsia, so it is important to let your OB-GYN know if you want to use it for headaches.

Do not take ibuprofen, aspirin, migraine medications, herbal products, or supplements during pregnancy unless your provider specifically says they are safe for you.
When to Call Your Healthcare Provider
Some headaches during pregnancy need urgent attention. The CDC lists a headache that will not go away or gets worse over time, vision changes, dizziness or fainting, fever, extreme swelling of the hands or face, chest pain, trouble breathing, and severe belly pain as urgent maternal warning signs.

Call your provider or seek urgent care if you have:
- A severe headache
- A headache that does not improve with rest, fluids, or provider-approved treatment
- A sudden “worst headache of your life”
- Vision changes, flashing lights, or blurry vision
- Dizziness or fainting
- Swelling of your face or hands
- Chest pain or trouble breathing
- Fever of 100.4°F or higher
- Severe belly pain
- High blood pressure readings, if you monitor at home
- Reduced baby movement later in pregnancy
Could a Pregnancy Headache Be Preeclampsia?
Sometimes, a bad headache can be a sign of a blood pressure problem such as preeclampsia. ACOG notes that headaches can sometimes be an early sign of preeclampsia, which is why severe or persistent headaches should be discussed with your OB-GYN. Source
Call your provider promptly if a headache comes with vision changes, sudden swelling, upper belly pain, shortness of breath, or feeling very unwell.
